MUSIC-LEAF TURNER.

Specification of Letters Iatent.

Application filed July 23, 1913.

Patented July 28, 1914.

Serial No. 780,748.

To all whom it may concern Be it known that I, FRANK E. GILES, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented new and useful Improvements in Music- Leaf Turners, of which the following is a specification.

The invention relates to music leaf turners, and more particularly to the class of electro mechanically operated music leaf turners.

The primary object of the invention is the provision of a music leaf turner wherein the sheets of a piece of music will be successively turned in a unique manner under the influence of an electric motor which is under the control of the player of a musical instrument.

Another object of the invention is the provision of a music leaf turner wherein the supporting frame for the piece of music is readily foldable so that it can be carried in a convenient manner and when not in use stored in the least possible space.

A further object of the invention is the provision of a music leaf turner which is simple in construction, capable of being mounted on a music rack, stand or the like, readily and easily operated, thoroughly reliable and efficient in its purpose, and inexpensive in manufacture.

WVith these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claim hereunto appended.

In the drawing :Figure 1 is a plan view of a music leaf turner constructed in accordance With the invention. Fig. 2 is a rear elevation thereof. Fig. 3 is a plan View showing the music leaf turner folded. Fig. 4 is a sectional view on the line 4l4 of Fig. 1.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing by numerals, the music leaf turner comprises a main support designated generally by the numeral 5, and includes a center bar 6 fixed medially to a base bar 7 which is arranged at right angles thereto and is formed in two parts connected together by means of a hinge 8, the pintle of the hinge being designed to connect the said bars 6 and 7 together so that the two parts of the bar 8 can be folded into alinement with the bar 6 when the music leaf turner is not in use. Pivotally connected with the bars 6 and 7 are foldable rack frames 9, each of which includes a series of hinged jointed sections designed to fold together so that the music leaf turner can be brought into compact form when not in use to permit the ready carrying thereof or the storage of the same in the least possible space. Suitably journaled on the bar 6 is a rotatable shaft 10 which is arranged in par allel relation to the said bar 6 and carries music sheet turning arms 11 provided with clips 12 for the fastening of the sheets of a piece of music thereto, the shaft- 10 being extensible so as to permit different sizes of sheet music to be supported by the music leaf turner. Integrally formed with the shaft 10 at its lower end is a. turning lever 12 to which is connected an operating cord 13, the same being trained over a guide pulley 14 j ournaled on the bar 7, the cord being connected with an electrically controlled motor 15 of the separately excited type which is carried by the bar 7 in any suitable manner. The motor 15 is connected in circuit with cells 16 which are suitably mounted upon the bar 7 and connected in the circuit is a foot operated pole changing switch 17 by means of which the flow of current through the circuit may be reversed so as to reverse the motor. The switch 17 if desired can be actuated by the foot or the hand of an operator or player of a musical instrument. The electric circuit is normally open so that the turning arms 11 will remain passive and on the closing of the electric circuit the motor will be started, thus causing the swinging of the arm successively for the turning of the sheets of the music in order.

From the foregoing it is thought that the construction and manner of operation of the device will be clearly understood, and therefore a more extended explanation has been omitted.

What is claimed is A music leaf turner comprising a center bar having spaced eye terminals at one end, base sections pivotally connected to the eye terminals, jointed braces pivotally connected to the center bar and to the outer ends of the base bars, foldable rack frames pivotally one of the base bars and having connection connected to the braces, pintle eyes formed with the lever for operating the same. 10 on the center bar, a turning shaft 10urnaled In testimony whereof I aflix my signature in the pintle eyes, spaced parallel music in presence of twowvitnesses.

" sheet turning arms fixed t0 the said shaft FRANK E. GILES.

and having clips a lever fixed to the lower lVitnesses: end of the shaft between the eyes, and an GEO. BLOOH, electrically controlled otor mounted upon VVM. E. HAYNE.
